Functioni

sGP seems to possess an anti-inflammatory activity as it can reverse the barrier-decreasing effects of TNF alpha. Might therefore contribute to the lack of inflammatory reaction seen during infection in spite the of extensive necrosis and massive virus production. Does not seem to be involved in activation of primary macrophages. Does not seem to interact specifically with neutrophils.
Delta-peptide does not seem to be involved in activation of primary macrophages.

Post-translational modificationi

Pre-sGP is N-glycosylated. This precursor is processed into mature sGP and delta-peptide by host furin or furin-like proteases. The cleavage site corresponds to the furin optimal cleavage sequence [KR]-X-[KR]-R. Both cleavage fragments contain sialic acid, but only the delta-peptide is O-glycosylated.1 Publication

RNA editingi

Edited at position 295.2 Publications
Partially edited. RNA editing at this position consists of an insertion of one or two adenine nucleotides. The sequence displayed here is the small secreted glycoprotein, derived from the unedited RNA. The sequence derived from the +1A edited gives rise to the full-length transmembrane glycoprotein GP (AC Q05320), the +2A edited RNA gives rise to the super small secreted glycoprotein ssGP (AC Q9YMG2).
